The amateur statistician will know that numbers this close for PS3 vs. 360 in a single week really amount to a statistical tie. However if over a period of weeks (with no major game releases to skew sales one way or the other) one system is constantly comeing out just ahead this points to a trend. Meaning one can reasonably confidently conclude that the system that is marginally ahead each week is selling slightly higher in reality.
There aren't enough weeks of sales post holidays yet to draw any conclusions, and PS3 was down this week on week while 360 was up (I wonder why?), so 360 could easily flip ahead next week.
That PS3 weekly sales are so close to 360 right now and is the only one of the 2 beating its 2009 numbers is certainly very good news for PS3. And by comparison with itself 360 is having a slow start to the year. This adds up to PS3 looking stronger relative to 360 even though weekly sales are pretty well even.
What was the reason for the massive Wii sales this time last year? Up until this week Wii was ahead of 2009, but it's looking like it is going to fall behind YoY pretty soon.
